Patented Oct. 11, 1938 UNITED STATES PATENT OFFICE 3 Claims.

This invention relates to new and useful improvements in shoes and more particularly it pertains to sole and upper constructions thereof.

One object of the invention is to provide a new and novel construction whereby a substantial and comfortable 'sole for shoes may be had.

A further object of the invention is to provide a new and improved manner of embodying in the shank of a shoe sole, a shank stitfiening member.

Still another object of the invention residesin the provision of a composite sole in which the filler medium will be retained in position in the shoe sole.

Still another object of the invention resides in a novel construction by which greater strength is obtained :and by which the shoe Vwill retain its shape to a better advantage than when the common construction is employed.

Other objectsl of the invention will become apparent as the nature thereof is better understood for which purpose reference is to be had to the following specification and claims and the accompanying drawing, in which:

Figure 1 is a longitudinal sectional view of a shoe embodying the invention,

Figure 2 is a plan view illustrating a skeleton midsole employed in the invention,

Figure 3 is a longitudinal sectional view taken substantially on the line 9- 9 of Figure 2,

Figure 4 is a longitudinal sectional view illus'- trating the complete insole,

Figure 5 is a transverse sectional view taken substantially on the line II-Il of Figure 1, and;

Figure 6v is a fragmentary sectional view illuse outwardly turned marginal flange which, however, does not'extend entirely around the marginal edge of the. upperv but instead, terminates at the point 4I in Figure 2, which'is substantially on the forward edge or breast of the sole 42. There is an inner sole 43, a welt member 44, and a skeleton midsole 45. The inner sole 43 the welt member 44 and the skeleton midsole 45 are secured together by a double line of stitching 46. The reference numeral 41 designates the outer sole and 48 designates an outer welt member and this outer sole, the skeleton midsole 45, the welt member 44, the marginal ange 40 of the upper and the outer welt member. are secured together by a line of stitching 49.

The skeleton midsole has a bridge piece 5l and secured to the bridge piece 5| as at 52 there is a shank stiiening element 53 which may be of any suitable stii material such as metal, stiE leather or the like. The skeleton midsole 45 together with its bridge piece 5| serves to space the inner and outer soles with respect to each other to provide for the reception of suitable cushioning material such as 55 which may be of any suitable compressible material.

In that form of the invention illustrated in Figure 12, the out turned marginal 'portion of the upper which, in said figure, is designated extends entirely around the outer edge of the shoe upper' and is secured to the outer sole at the rear of the shoe by means of an outer welt member 6I and a plurality of rows of stitches 62 Ywhich extend through the insole 43, the welt member 44, and the skeleton midsole 45. Also in this form of the invention the shank stifiener 53 is secured at its rear end as at 63 to the heel portion of the skeleton midsole 45, as distinguished from that form of shank stiiener illustrated in Figures 1 through 4 in which the rear end of the shank stiiener member 53 is not at;-

,tached to either the inner sole or the skeleton midsole.

From the foregoing it will be apparent that the present invention provides a new and improved construction of shoe in which the objects heretofore recited are obtained and in which the advantages recited are present.

Having thus described the invention, what is claimed as new, is:

1. In a shoe construction, an upper, an inner sole. a. welt member secured directly to the inner sole, a skeleton midsole secured to the inner sole, and spaced therefrom by the welt member, an outer sole, said outer sole being spaced from the inner sole vby the skeleton midsole and the welt member to provide a space or chamber in'which is disposed a cushioning material, and a shank stiffener mounted in the space or chamber between the inner and outer sole, said shank stiiI- ener being rigidly attached to the skeleton midsole at its forward end only.

2. In a shoe construction, an upper, an inner sole, an outer sole, means for securing the inner sole and the outer sole in spaced relation to provide an intervening space, said means including a skeleton midsole having a transverse bridgev portionintermediate of its ends, a cushioning material positioned in the space between the inner and outer sole and in the spaces of the skeleton midsole, and a shank stiiener connected to the transverse bridge portion of the skeleton midsole and extending rearwardly from its point of attachment. y

3. In a shoe construction, an inner sole, a

midsole secured to the Welt member and inner' sole, said skeleton midsole having its inner edge extending beyond the inner edge of the welt member, a transverse bridge extending across the skeleton midsole intermediate of its ends, a shank stifiener secured to the inner face of the transverse bridge in the space between the transverse bridge and the inner sole, said shank sti'ener extending rearwardly from its point of attachment, an upper secured to the marginal edge of the welt member, an outer sole secured tothe outer face of the skeleton-midsole and spaced yfrom the inner sole, and a ller filling the space between the inner sole and the outer sole.
